Interfacing to ON Semiconductor Demo3 Baseboard
The ON Semiconductor Demo3 baseboard has a similar
52 − pin connector P5 which mates with J1 of the headboard.
The four mounting holes secure the baseboard and the
headboard with spacers and screws.
Shorted Jumpers for Power Measurement
Different supplies to the evaluation board are provided by
trace shorted jumper, for any voltage and power
measurements. To conduct current measurement on a given
power rail, cut the trace between the two pins of their
respective JP, and insert an ammeter prior to powering up the
system. The figure below shows where the trace to cut is
located.
